Pram with at least one adjustable handle

ABSTRACT

The invention is directed to a pram or buggy with a frame, a plurality of wheels, an upper part and at least one height- and/or rotationally-adjustable handle ( 3 ), wherein the handle/the handles is/are coupled or connected to at least one element which enters into a (respective) tube ( 2 ) of the frame and the cross section of which is (slightly) smaller in a first state than the internal cross section of the tube and, in a second state, can be at least partially pressed or spread outwards in order to be securely gripped within the tube.

The invention is directed to a baby carriage, stroller or the likehaving a chassis, plural wheels, a superstructure and at least oneheight-adjustable handle.

Since baby carriages, strollers and the like are pushed by differentpeople, there is a need for their handle(s) to be made adjustable interms of height, and in as infinitely variable a manner as possible. Inaddition, in the case of two mutually separate handles, as opposed to apushbar, there is also frequently a need to adjust the handles todifferent pivot angles, i.e., for example, pointing toward each other ina line, or thrust upward and roughly parallel, or other positionsbetween or beyond these settings.

Moreover, strollers—previously also known as “sport carriages”—are oftenused, for slightly older children, as easily transportable childtransport devices that can, for example, be collapsed with fewmanipulations and quickly stored in the trunk of an automobile, e.g. fora Sunday drive or the like. The possibility of quick knockdown andsetup—without elaborate handling—is especially important in this case,and this also naturally applies to handles or pushbars.

In addition, the mechanisms suitable for this purpose should notincrease the price of the baby carriage or stroller unnecessarily.

The foregoing considerations have given rise to the problem initiatingthe invention, that of fashioning the handles of a baby carriage ofstroller, using an inexpensive mechanism, so that they can be adjustedand locked quickly and easily, said mechanism also being suitable forconnection to, addition to or incorporation into a tube of the chassisof a baby carriage or stroller.

This problem is solved in that the handle or handle(s) is/are (each)coupled or connected to a (respective) element which immerses in a tubeof the chassis and whose cross section(s), in a first state, is/are(slightly) smaller than the inner cross section of the tube, and whichin a second state can be at least partially pressed outward or spread soas to wedge itself firmly inside the tube.

A wedging arrangement of this kind makes it possible to lock the handlein any desired heightwise and/or rotational position, and thus to adjustit in an infinitely variable manner. This adjusting mechanism is alsorelatively easy to construct, and is therefore economical. In addition,it is suitable for incorporation into the chassis of a baby carriage orstroller.

If, as the invention further provides, at least one adjustable elementis configured as an elastic ring, the outer circumference of thatelement can be forcefully pressed apart in the radial direction. A ring,i.e., a double-connected body, in contrast to a single-connected body,is only indirectly subject to a force acting against radial expansion,specifically in the form of an inner tension that opposes an increase inits circumference. The very elasticity of the body allows it to undergobroad, nondestructive expansion in the presence of comparatively littletension. In addition, a radially outwardly directed force might also beapplied directly to the inner face of the ring. Such radial spreadingwould cause radial pressure to build up inside the annular body, thusforcing its outer jacket outward.

It has proven advantageous to provide that at least one elastic ring beexposed to axial pressure. This measure also ultimately has the effectof causing the outer jacket to spread out radially, since the annularbody attempts to avoid axial compressive deformation by stretching inthe radial direction while still maintaining its (radial) proportions,which can occur only in conjunction with an increase in its outercircumference. (Largely) homogeneous (elasticity) properties of theannular body make it possible to convert a comparatively low tensioninto relatively intense, nondestructive deformation.

An axial pressure can be created between the two end faces of theannular body in a particularly structurally simple manner through theuse of two elements that are mutually adjustable in the axial direction,between which the annular body is disposed and which can, if necessary,be wedged in place.

The invention can be refined by having the two elements that aremutually adjustable in the axial direction be arranged concentrically toeach other, correspondingly to the roughly constant cross section of atube of the chassis of a baby carriage or stroller. The wedging elementscan preferably each be a disk-shaped, particularly acircular-disk-shaped or annular-disk-shaped or ring-shaped body,preferably made of metal or a similarly firm or rigid material.

A preferred particularity of the invention resides in the fact that thedistance from the spreadable body to the handle or its connecting jointis constant, i.e., fixed. The spreadable body can thus be adjusted alongwith the handle, i.e., the elements axially embracing the spreadablebody and, where appropriate, compressing it. This can be achieved byhaving two bodies that generate axial pressure be connected to theadjustable handle unit. Such connection can be effected, for example, bymeans of rods and/or tubes, or, where appropriate, by means of a wire orother traction means.

On the premise that a rotationally symmetrical arrangement creates aneven force distribution and thus avoids undesirable seizing of theadjustable unit inside a tube, preference is to be given to anarrangement in which one of the two mutually adjustable elements isconfigured as a tube, sleeve or the like, and the other as a rod, atube, and/or as a wire or other traction means, that extends throughsaid tubular or sleeve-shaped element.

Naturally, a rod, tube or the like connected to the lower clampingelement must extend through the elastic ring(s) in order establish aconnection to the handle unit.

A rod, tube or the like that extends through the spreadable bodiesshould widen cross-sectionally beyond, i.e. below, the elastic Ring(s),for example by means of a screwed-on disk, so as to engage an annularbottom end face of the spreadable body from below.

To transmit the rotational position of a firmly wedged spreadable bodyto a handle with as little torsion as possible, twisting of theconnecting rods should be avoided, insofar as possible. To this end, theinvention recommends that the rod have a cross section that deviatesfrom the circular, for example an elliptical, elongate, X-shaped orstar-shaped cross section. Such a design specification takes account ofthe fact that radially more, outward-lying regions of a connectingprofile are more torsionally rigid than more inward-lying regions. Anideal cross-sectional shape is furnished, for example, by connectingtubes. Such a geometry should therefore also include a centralconnecting profile.

A central rod, tube or the like should be displaceable in the axialdirection in relation to a rod, sleeve or the like surrounding it. Thispermits relative axial adjustment between these two elements, and thusalso between disks that encompass the spreadable bodies on theirrespective top and bottom faces.

The locked or adjusted state of the spreadable body can be chosen bymeans of a lever that is disposed, particularly articulated to or formedon, the top end of a rod, sleeve and/or tube. This can be accomplishedparticularly by having the pivot position, rotational position and/orother position of the lever coupled to a device for changing thepressure on or in the spreadable body, in order to relay thisinformation.

The pivot axis of the lever is preferably oriented transversely to thelongitudinal axis of the rod and/or of the sleeve, since such a movementof the spreadable body cannot be effected through the guide tube of thechassis of the baby carriage. The adjusting movement of the handle thusis completely decoupled kinematically from the selecting movement of thelever, thus making it possible to integrate these two elements—handleand selection lever—together into one module or even into a single part.

Taking the inventive idea further, at least one lever can have at itsarticulated end a jacket portion that surrounds the pivot axis at leastregionally along the longitudinal direction thereof. This jacket portioncan be used to convert a change in the pivot angle of the selectionlever into an (approximately) axial displacement of a part coming intocontact with the jacket surface.

The jacket portion surrounding the pivot axis can extend eccentricallyto this pivot axis in such a way that the distance of its circumferencefrom the pivot axis changes in the circumferential direction in acam-like manner.

To the extent that such a cam-shaped circumferential portion rests on anend-face region of the sleeve or the like, it communicates theeccentricity of the jacket surface, which depends on the pivot angle ofthe selection lever, to an element pressing on the spreadable body,preferably the upper pressing element.

Alternatively or cumulatively thereto, a traction element can beprovided to pull upward on a pressing element, preferably the lower one,in a certain angular position of the selection lever, and thus (also) toexert pressure on the respective surface, specifically the bottomsurface, of the spreadable body. Such a traction element can electivelybe configured as a rod, a tube, or alternatively as a wire or otherflexible but minimally or non-expandable traction means.

It is within the scope of the invention that disposed on and outwardlyembracing the sleeve is a cuff that can be fixed in and/or on the guidetube, for example that snaps into recesses thereof or extends throughthe guide tube and/or outwardly embraces it.

Finally, it is within the teaching of the invention that provided at thetop end of the tube is an end cap that serves to guide the sleeve. Suchan end cap can also be configured to snap into recesses in the guidetube and/or so as to encompass and/or embrace it from the top or theoutside.

Other features, details, advantages and effects based on the inventionwill emerge from the following description of a preferred embodimentthereof and by reference to the drawing. Therein:

FIG. 2 shows the handle insert of the arrangement from FIG. 1 withoutthe surrounding guide tube, from approximately the same perspective,also in the locked state;

FIG. 3 is a longitudinal section through FIG. 1;

FIG. 4 shows the arrangement from FIG. 1 in a similar view, but in therotationally and displaceably adjustable state;

FIG. 5 is a longitudinal section through FIG. 4; and

FIG. 6 is a depiction similar to FIG. 2 of a modified embodiment of theinvention.

A typical commercial baby carriage, stroller or the like is equippedwith two handle units 1, each of which is longitudinally displaceablyand fixably guided in a respective tube 2 of the chassis of the babycarriage.

In this system, the actual handle 3 is outside the guide tube 2, whereasthe adjustable wedging mechanism 4 is inside the guide tube 2. A cuffthat surrounds the tube 2 externally could be provided at a level belowthe handle 3, for esthetic reasons, for example, but also to keep outany rainwater that might enter the tube 2 from above; such a cuff is notillustrated in the drawing, however.

In the embodiment according to FIGS. 1 to 5, the handle 3 per se isillustrated in a simplified manner in the form of a lever 5; naturally,it could have an ergonomic shape, for example with depressions fashionedin it as deepened seats for individual fingers, etc.

This lever 5 is journaled to or connected to a pivot axis 6 extendingtransversely to the longitudinal axis of the tube 2. Said pivot axis 6is held or journaled, on both longitudinal sides of the lever 5, in apart 7, specifically between two approximately parallel bearing platesor bearing shields 8.

As can be appreciated from FIG. 3, setting aside the formed-on bearingshields 8, said part 7 has approximately the shape of a sleeve withrelatively thick walls, such that only a small passage 9 with a diameterof, for example, 1 mm to 5 mm, particularly about 2 mm to 4 mm, remainsat the center.

Setting aside the bearing shields 8 and the central through-opening 9,part 7 has approximately the shape of a stopper for sealing the tube 2;however, its outer diameter is smaller than the inner diameter of thetube 2, and it is received in a relatively thin-walled sleeve 10 whoseinner diameter is adapted to the outer diameter of part 7, for examplein the manner of a press fit or transition fit.

The sleeve 10 has a wall thickness of, for example, 0.5 mm to 2.5 mm,particularly of 1 mm to 2 mm, and it is longer than part 7, for exampletwice as long or even longer.

The outer diameter of the thin-walled sleeve 10 is smaller than theinner diameter of the tube 2, allowing them to slide frictionlessly oneinside the other. The sleeve 10 is rotatably and displaceably guided bya guide cuff 11 at the top end of the tube 2.

The outer diameter of this guide cuff 11 is adapted to the innerdiameter of the tube 2, while its inner diameter is adapted to the outerdiameter of the thin-walled sleeve 10, in each case preferably more orless in the manner of a loose fit or a transition fit. The guide cuff 11is fixed form-lockingly inside the tube 2, for example by means of aradially outwardly projecting rim or collar 12 disposed at its top endand resting on the end face of the tube 2, and/or by means of radiallyoutwardly jutting protrusions 13 that snap into mating depressions orrecesses 14 in the jacket of the tube 2. While the guide cuff 11 isimmovably fixed in the tube 2 by these protrusions 13 and/or by thecollar 12 it has at its top end, for the sleeve 10 it forms a sort ofsliding guide that permits relative displacement and/or relativetorsion, but prevents caught edges or other tilting.

Sleeve 10 is encompassed at its top end by a circumferential collar 15of part 7, disposed in the region of the edge between the jacket surface16 thereof and the upper end face 17 thereof, and thus can be displacedin relation to part 7 only until it butts against this collar 15.

Disposed below the bottom end of sleeve 10 is a first perforated disk 18that has an approximately annular base area and is intersected at rightangles by the longitudinal axis of the tube 2. The bottom edge of thesleeve 10 rests on the upper face of perforated disk 18 and can beconnected, for example glued, soldered or welded, thereto, although thisis not absolutely necessary for the function.

Disposed below first perforated disk 18 is a second perforated disk 19,which is preferably approximately coincident with the first. It is notimmediately adjacent the first perforated disk 19, however, but extendsin spaced relation to and below first perforated disk 18, preferablyparallel thereto. An annular body 20 is preferably disposed betweenthem.

Said annular body 20 has approximately the shape of a right circularcylinder with mutually parallel and coincident end faces, and through itpasses a central through-opening 21 concentric with the longitudinalaxis of the cylinder. Annular body 20 is preferably made of an elasticmaterial, such as rubber, for example.

A traction means, for example a metal wire 22, extends concentricallywithin the tube 2, passing through the through-opening 14 of part 7, theupper perforated disk 18, the annular body 20 and the lower perforateddisk 19.

Beneath lower perforated disk 19, the traction means or metal wire 22 isprovided with a thickening, for example owing to a knot that is presentthere, or a bead 23 or the like through which the traction means ormetal wire passes and which is fixed, for example firmly glued, thereto.

Since the diameter of the bead 23 or other thickening is larger than theinside diameter of the central opening in lower perforated disk 19, thetraction means or metal wire 22 is unable to slip through it.

The upper end of the traction means or metal wire 22 is connected to thelever 5 of the handle 3. The lever 5 has a short region for this purposeon the far side of the pivot axis 6, and thus is effectively configuredas a two-armed lever, although the handle 3 per se is very short incomparison to horizontal arm 24, i.e., approximately comparable to thethickness of lever 5, measured in a cross-sectional plane that isintersected at right angles by the pivot axis 6, particularly having amaximum length that is approximately between half the thickness of thelever 5 and the whole thickness thereof.

The top end of the traction means or metal wire 22 is anchored in or tothis short arm 24, preferably on a plane spanned by the longitudinalaxis of the handle 3 and by the pivot axis 6. An anchoring bore 25extending parallel to the pivot axis 6 is preferably provided for thispurpose in the second arm 24 of the lever 5, preferably along thecentral plane thereof. This can be configured as a through bore or ablind bore. It is, however, connected by a slit 26—for instance, alonghalf the width of the handle 3—to the end face of the second lever arm24. Whereas the width of the slit is approximately equal to the diameterof the traction means or metal wire, the diameter of the anchoring bore25 located behind it is much greater, for example twice as large.

Also disposed at the top end of the traction means or metal wire 22 is athickening, which, as in the case of the one provided at the bottom endof the traction means or metal wire 22, can be formed, for example, by aknot; or, alternatively, by an element that is affixed to the end ofsaid traction means and has said traction means extending through it orencompassing it, and is connected thereto, for example by a glued,soldered or welded joint; or, alternatively, by a knot or the like. Thediameter of the thickening is greater than the width of the slit 26, butsmaller than the diameter of the anchoring bore 25 in the second arm 24of the lever 5. The thickening can thus be pushed from a mouth of theanchoring bore 25 on into the latter, thus causing the traction means ormetal wire 22 itself to pass through the slit 26. The thickening can befixed, for example with glue, inside the anchoring bore 25. Whereappropriate, however, the (optionally thickened) end of the tractionmeans or metal wire 22 can also be overmolded with a lever module 5, 24made of plastic in an injection molding process, and thus inseparablyconnected thereto.

From its exit point from the slit 26, the traction means or metal wire22 bends downward to the tube 2 and ultimately passes into the mouth ofthrough-opening 14 in part 7.

If lever 5 or handle 3 extends approximately in the direction of thelongitudinal axis of tube 2, as depicted in FIG. 5, then the anchoringbore is approximately on the longitudinal axis of tube 2, not far fromthe upper mouth thereof. The length of the traction means or metal wire22 is so calculated that in this state it can extend without tensionfrom handle 3 all the way to lower perforated plate 19.

The wedging mechanism 4 is free of forces in this state, and annularbody 20 thus resumes its original shape, in which its outer diameter isslightly smaller than the inner diameter of tube 2. The latter thus canbe displaced freely within the tube 2, specifically slid up and down, inorder to adjust the heightwise position of the handle 3, and rotated tothe left and the right in order to adjust the rotational position of thehandle 3 in relation to the tube 2.

As soon as a mother or other caregiver has thereby found a personallysuitable position for the handle 3, the lever 5 of the handle 3 ispivoted downward from the position according to FIGS. 4 and 5 into theposition according to FIGS. 1 to 3. As will be appreciated particularlyby comparing FIGS. 3 and 5, in this process the anchoring bore 25migrates distinctly away from its initial position near the mouth oftube 2: in FIG. 3, it is situated roughly at the same level as pivotaxis 6, rather than beneath it, and is also shifted to one side. Thiscauses the traction means or metal wire 22 to be pulled a little way outof the tube 2. At the same time, lower perforated plate 19, throughwhich the traction means passes but which it cannot slip out of becauseof its bottom thickening, is carried along upward, whereas upperperforated plate 18, which has no contact with the traction means ormetal wire 22, is not. The (vertical) spacing between the two perforatedplates 18, 19 is decreased commensurately as a result.

This distance, however, is now smaller than the height of elasticannular body 20. The latter is therefore compressively deformed in theaxial direction, i.e., in a direction parallel to the longitudinal axisof the tube 2. It attempts to avoid this deformation by simultaneouslyexpanding in the radial direction, particularly radially outward. Butsince its original outer diameter is only slightly smaller than theinner diameter of the tube 2, in so doing it comes into contact with theinner face 27 of the tube 2. Since the tube preferably consists of arigid material, for example metal, it does not yield, but resists theradial pressure of the annular body 20. The latter thus is pressedfirmly, and thus friction-lockingly, against the inner face 27 of thetube 2, and is thereby, so to speak, immovably locked in place.

In this way, body 20, fixed in tube 2, communicates its verticalposition and its rotational position via upper perforated plate 18,sleeve 10, part 7 and pivot axis 6 to lever 5 or handle 3, and alsofixes the latter in relation to the tube 2. The handle 3 is now lockedin the desired position, and the baby carriage can be used.

FIG. 6 shows a modified embodiment of the invention. The sole differencebetween this embodiment and the one described previously, however, isthat the two bearing plates or bearing shields 8 are extended in theirplane in one direction, specifically each in the same directiontransversely to the longitudinal axis of the tube 2. This gives each ofthe two bearing shields a longish shape in the form of an elongatedplate 28. These two plates extend approximately parallel to each otherat a roughly constant distance apart, and they are connected to eachother by a central web in the region of their respective bottom edges,i.e., at approximately the (axial) height of the upper end face of body7. The overall effect is to yield more or less the shape of a lateralattachment 29 having an approximately U-shaped cross section.

The cross section of the trough within this attachment 29 isapproximately identical to or slightly larger than the cross section oflever 5, such that lever 5, when pivoted downward, can sink withoutproblems into the trough of attachment 29, as can be seen in FIG. 6.Attachment 29 is meanwhile able to embrace lever 5 along its entirelength, and preferably also along its entire height.

The whole formed by attachment 29 and lever 5 pivoted thereintoconstitutes the handle 3′ in this embodiment. The advantage here is thatwhile adjusting the handle 3′, a person can constantly monitor theadjusted height and rotational position by referring to attachment 29,before locking these settings in place by pivoting the lever 5 downward.

The outer conformation of attachment 29 can be ergonomically designed,for example by means of engaging indentations or the like.

Various other modifications of the invention are conceivable. Forinstance, instead of a single annular body 20, a plurality of suchbodies can be used, for example arranged behind or above one another inthe axial direction; these can be directly adjacent each other orseparated by interposed plates.

A form lock to prevent relative torsion could be created between theannular body or bodies 20 and the adjacent perforated plates 18, 19,particularly in the region of upper perforated plate 18, for example bymeans of prolongations formed on a perforated plate 18, 19 or bystamping and bending tabs out of a perforated plate 18, 19, whichprolongations, bent tabs or the like are then able to fit into matingdepressions in the annular body or bodies.

In addition, instead of a flexible traction means or metal wire 22, itis also feasible, where appropriate, to use a rod or even a tube or anoptionally bent wire, or alternatively a chain or the like.

In the preferred embodiment, in the firmly wedged state an axialpressure is exerted on the annular body or bodies 20, decreasing thedistance between two elements that engage this body or these bodies 20from above or below, for example (perforated) plates or (perforated)disks 18, 19. This state should be stable in the absence of any externalforces. This can by brought about, for example, by means of inhibitingfrictional forces in a bearing part 6, 8 or by means of a geometricarrangement, for example after the fashion of a toggle lever, whose endpositions are stable, or alternatively by means of a latching action,for example between the lever 3′ and a prolongation 29 that embraces it.

In another state, on the other hand, little or no axial pressure isexerted on the annular body or bodies 20. This released state ispreferably, but not necessarily, stable in the absence of externalforces; it could, for example, be switched to the other, firmly wedgedstate by a restoring spring element, such that the resetting springelement would always have to be overcome to effect release andadjustment.

Various measures for switching from the released to the firmly wedgedstate may be contemplated. For one thing, an upwardly directed(additional) traction can be exerted on the element 19 engaging theannular body 20 from below, and/or a downwardly directed (additional)pressure is exerted (for example, by means of a cam on a pivotable lever5) on the element 18 engaging the annular body 20 from above; either thetwo measures are combined with each other, or the respective otherelement 18, 19 is held fast during this process, for example by beingconnected to or integrated into the handle 3 or a bearing 8 thereof.
